This paper aims at designing a new algorithm for digital filters. The traditional methods like FIR, IIR have been improved in recent times with new approaches. However, the developments have used complex arithmetic calculation and dedicated DSP processors. In this research project, effort has been made to reduce such complexities using a procedure based on the technique of Conditional Averaging. The entire algorithm is developed using more of conditional statements and less of arithmetic... Topics: FFT, DSP, LPF
The crew compartment of the Full Fuselage Trainer, used for decades to train space shuttle crews at NASA's Johnson Space Center, is packed for shipping to the Museum of Flight in Seattle. This first of three large sections of the trainer, which contains the shuttle cockpit, will be transported inside NASA's Super Guppy aircraft this month for a welcome ceremony in Seattle planned for June 30.

A new parallel pipelined feed forward architecture for real-time signal is proposed. A hardware oriented radix-2 algorithm is derived by integrating a twiddle factor decomposition technique in the divide and conquer approach. The butterfly structure of radix-2 algorithm is modified in accordance with the flow of signal. The new butterfly structures are designed to handle the hybrid data path which consists of real & complex data paths. The proposed approach which can be extended to all...

In this paper a bank of velocity filters is devised tobe used for isolating a moving object with specific velocity(amplitude and direction) in a sequence of frames. Theapproach used is a 3-D FFT based experimental procedurewithout applying any theoretical concept from velocity filters.Accordingly, each velocity filter is built using the spectralsignature of an object moving with specific velocity.Experimentation reveals the capabilities of the constructedfilter bank to separate moving objects...

The biometric technology is used to identify individuals effectively compared to existing traditional methods. In this paper we propose Bimodal Biometric System using Multiple Transformation features of Fingerprint and Iris (BBMFI). The iris image is preprocessed to generate iris template. The two level Discrete Wavelet Transformation(DWT) is applied on iris template and Discrete Cosine Transformation (DCT) is performed on second level low frequency band to generate DCT coefficients which... Topics: Fingerprint, Iris, DWT, DCT, FFT, Euclidean distance.

A significant problem in Multicarrier Code Division Multiple Access (MC-CDMA) system is the possibility of high Peak to Average Power Ratio (PAPR). This is dueto the cumulative sum of N subcarrier peaks in the transmitted signals which reduces Powerefficiency, resolution and battery life. In this paper a technique is proposed to make use ofInverse Discrete Cosine Transform (IDCT) and Inverse Discrete Wavelet Transform(IDWT) based Multicarrier Code Division Multiple Access (MC-CDMA) system....

This paper presents an Orthogonal Frequency Division Multiplexing (OFDM)transceiver that makes use of a low power Fast Fourier Transform (FFT) along with a LeastMean Square (LMS) filter. The folded FFT is developed via folding transformation andregister minimization techniques with real values as inputs which leads to reduction inhardware complexity by exploiting the redundancy present in computing the FFT samplesand also the amount of power consumed. A LMS filter is also designed for the... Topics: Folded FFT, LMS filter, OFDM, Power consumption, noise variance, MSE.
Digital broadcasting, internet audio and music database make use of audiocompression and coding techniques to reduce high quality audio signal without impairing itsperceptual quality. Audio signal compression is the lossy compressiontechnique, Itconverts original converting audio signal into compressed bitstream. The compressed audiobitstream is decoded at the decoder to produce a close approximation of the original signal.For the purpose of improving the coding this work attempts to verify the...

Next generation communication network will be required to provide increased data rate efficiently along with the flexibility to adapt to various dynamic traffic patterns in a cost effective manner. The optical fiber communication system can do the same along with low losses and good quality of transmission. In the recent past, the enormous growth of network traffic on deployed optical communication networks forced the demand for a more constructive utilization of the channel capacity of the...

Every physical move we make is triggered by neural processes in the brain. With the right equipment and recent developments in both brain imaging technologies and cognitive neuroscience, it is possible to read and record these processes. This has led to the rapidly growing field of brain computer interfaces (BCI). The Brain Computer Interface (BCI) helps unblessed people to make use of the devices and applications through their mental activities. So people believe that BCI technology is a...

Unified omniscient methodologies have led to many confirmed advances, including forward-error correction and linked lists. In fact, few analysts would disagree with the synthesis of the UNIVAC computer, which embodies the intuitive principles of theory. Outflow, our new method for forward-error correction, along with Fourier Transform, is the solution to all of these grand challenges.
